28XS::APItest - Test the perl C API
29
30=head1 SYNOPSIS
31
32  use XS::APItest;
33  print_double(4);
34
35=head1 ABSTRACT
36
37This module tests the perl C API. Currently tests that C<printf>
38works correctly.
39
40=head1 DESCRIPTION
41
42This module can be used to check that the perl C API is behaving
43correctly. This module provides test functions and an associated
44test script that verifies the output.
45
46This module is not meant to be installed.
47
48=head2 EXPORT
49
50Exports all the test functions:
51
52=over 4
53
54=item B<print_double>
55
56Test that a double-precision floating point number is formatted
57correctly by C<printf>.
58
59  print_double( $val );
60
61Output is sent to STDOUT.
62
63=item B<print_long_double>
64
65Test that a C<long double> is formatted correctly by
66C<printf>. Takes no arguments - the test value is hard-wired
67into the function (as "7").
68
69  print_long_double();
70
71Output is sent to STDOUT.
72
73=item B<have_long_double>
74
75Determine whether a C<long double> is supported by Perl.  This should
76be used to determine whether to test C<print_long_double>.
77
78  print_long_double() if have_long_double;
79
80=item B<print_nv>
81
82Test that an C<NV> is formatted correctly by
83C<printf>.
84
85  print_nv( $val );
86
87Output is sent to STDOUT.
88
89=item B<print_iv>
90
91Test that an C<IV> is formatted correctly by
92C<printf>.
93
94  print_iv( $val );
95
96Output is sent to STDOUT.
97
98=item B<print_uv>
99
100Test that an C<UV> is formatted correctly by
101C<printf>.
102
103  print_uv( $val );
104
105Output is sent to STDOUT.
106
107=item B<print_int>
108
109Test that an C<int> is formatted correctly by
110C<printf>.
111
112  print_int( $val );
113
114Output is sent to STDOUT.
115
116=item B<print_long>
117
118Test that an C<long> is formatted correctly by
119C<printf>.
120
121  print_long( $val );
122
123Output is sent to STDOUT.
124
125=item B<print_float>
126
127Test that a single-precision floating point number is formatted
128correctly by C<printf>.
129
130  print_float( $val );
131
132Output is sent to STDOUT.
